Total a column with SUM
The first formula everybody learns, and the one place a typed-out chain of plus signs still costs people an afternoon.
The data
| Row number | A | B |
|---|---|---|
| 1 | Month | Revenue |
| 2 | January | 4200 |
| 3 | February | 3850 |
| 4 | March | 5100 |
| 5 | April | 4650 |
| 6 | May | 5300 |
Your task
Put a formula in B7 that totals every revenue figure in column B.
Your formula goes in B7
The checker compares your formula against the accepted answers — it does not run it. The expected result is shown with the solution so you can verify it in your own spreadsheet.
Why this is the right formula
Writing =B2+B3+B4+B5+B6 gives the same answer today and breaks the moment somebody inserts a row for a new month — the chain simply skips it. SUM takes a range, so an inserted row inside B2:B6 is picked up automatically. That difference is why SUM exists at all.

Questions
Does this actually run my formula?
The checker normalises case, spaces, argument separators and dollar-sign anchors, then compares your formula with a reviewed list of accepted answers. It does not evaluate the formula. Copy the data into your spreadsheet to verify the expected result independently.
Can a correct formula be rejected?
Yes. The accepted list includes several reviewed approaches, but cannot recognise every equivalent formula. Compare an unlisted solution with the expected result in your spreadsheet and use the page feedback if an accepted answer is missing.
